Title: Suspension system
Inventor: HALL BRIAN BARRIE
IPC: B60G17/018
Filed: 1994-10-27
Abstract: In an active or semi-active vehicle suspension system, control means 17 controls a valve 15 regulating the flow of fluid to or from fluid struts of the suspension system in accordance with inputs 17a representing a number of suspension characteristics. The controller operates on the inputs 17a in accordance with the formula      qd =  SIGMA Knxn,  where      qd is the required flow rate      Kn is a series of operating states and Xn is a series of predetermined gains selected to reproduce the dynamics of an equivalent analogue system. A Kalman filter KF may be used to estimate some of the inputs 17a from measured quantities 21, 23 and 25. Also disclosed is a flow controller which operates on the valve control signals in a manner dependent on the pressure drop across the valve thus taking account of the non-linearity of the operation of the control valve. <IMAGE>

Title: Auxiliary-signal transmission system
Inventor: SHIMA MICHIKAZU
IPC: H04B10/61
Filed: 1995-02-16
Abstract: Spontaneous emission occurring in association with direct optical amplification using an erbium-doped optical fiber is modulated with an auxiliary signal, such as a supervisory signal, for transmission of the auxiliary signal. The output of an optical amplifier 2 is passed through a variable optical band-pass filter 31 whose pass band is varied in accordance with the auxiliary signal, to modulate the spontaneous emission component contained in the optical amplifier output. In a receiver (Fig. 3) the output of the optical amplifier 2 is separated by an optical branching device (4) into a main optical signal and part of the spontaneous emission. An appropriate repeater is disclosed (Fig. 5). In an alternative embodiment spontaneous emission component is separated (35) and modulated by being passed through a variable optical band-pass filter (31) whose passband is varied in accordance with the auxiliary signal, and then the modulated spontaneous emission component is wavelength-division multiplexed (37) with the main optical signal. <IMAGE>

Title: Clipping processing device, three-dimensional simulator device, and clipping processing method
Inventor: TAKEDA MASAKI
IPC: G06T15/30
Filed: 1994-09-28
Abstract: This invention aims at providing a high speed clipping processor which is most suitable for a three-dimensional simulator particularly for executing image processing on a real time basis. An initial value is set from an initial value setting portion (152) to a priority register (170) and index data on a clipping surface is stored from the highest-order register to a lower-order register. A clipping operation portion (200) executes a clipping operation for a polygon from the clipping surface of the index data sequentially read out from a readout portion (190). When clip-out is made from a certain clipping surface, the index data of this clipping surface is written into the highest-order register of the priority register (170) and the index data stored in the lower-order registers are sequentially written into the subsequent lower-order registers. As a result, priority stored in the priority register (170) can be made optimal, and high-speed performance of the clipping processor can be accomplished. <IMAGE>

Title: Easy-open beverage container
Inventor: ELLIOT DAVID
IPC: B65D17/00
Filed: 1995-10-24
Abstract: A container 1, such as a drinks can, comprises a surface 2 with an integral discrete area 4 bounded by a line of weakness 5, the discrete area having a recessed portion C and a projecting portion A, B with a curved edge 7, surface B of the projecting portion being a rising slope which receives pressure and surface A being a falling slope which transmits pressure to the line of weakness 5 producing a break at point 8 which progressively spreads around the line of weakness. The point of initial opening 8 may be part of the line of weakness or may be an aperture sealed by a gasket or plastisol closure to provide a weak zone from which the break can propagate. The pressure receiving surface B may be planar and at 45 degrees to the plane of the surface 2. Preferably the discrete area is housed in the top plate surface which is press-fitted or spun over the rim of the container side-wall and the line of weakness bounding the discrete area is created by scoring or kiss-cutting. There may be a break 6 in the line of weakness which acts as a hinge preventing the discrete area from fully detaching from the top plate surface. The central area of the top surface 2 may be raised to enhance the opening action (figures 5 - 7). The recessed portion C may comprise separate concertina areas (1, 2, 3 figure 9) to allow the entire discrete area to move horizontally on opening. The container may have an inwardly conical tapering top plate with an annular retroverted portion to provide protection against the sharp edge (figures 13 - 17). <IMAGE>
Patent GB-956264-A (GB)
Abstract: 956, 264. Gyroscopic apparatus. UNITED AIRCRAFT CORPORATION. Nov. 27, 1961 [Jan. 5, 1961], No. 42261/61. Heading G1C. In an inertial navigation system gyroscope drift is eliminated by a self contained automatic trimming system. The local level system has accelerometer 24 detecting NS acceleration, accelerometer 54 detecting EW acceleration and rate gyros having input axes 21-EW; 51-NS; 81-vertical with associated amplifiers 22, 52, and servos 23, 53, so that the platform is normally maintained level whilst the output of accelerometer 24 is integrated through amplifier 91, velocity servo 92 and potentiometer 94 and applied to azimuth gyro 81 to force the platform to maintain a northerly orientation as a gyro compass. The output of accelerometer 54 is integrated, through amplifier 61, velocity servo 62 and potentiometer 64 and fed to gyro 51 to eliminate the major portion of drift therein, a residual drift error remaining which varies as the square of the error in northerly orientation, which is small compared with its normal drift. Assuming therefore that gyro 51 is drift-free a motor 5 is started to begin a switching operation causing, through switch 90, the accelerometer 54 to control the gyro compassing of azimuth gyro 81 and, through switch 10, earth rate to be applied to gyro 21 instead of gyro 51. The gyros 21, 51, and accelerometers 24, 54 have thus been changed over in function, the platform slews through 90 degrees and, through integrator 31, 32, 34, the output of accelerometer 24 is applied to gyro 21 to practically eliminate drift in that gyro. The platform is now oriented almost exactly north so that the residual drift, varying as the square of a very small angular error from north, is extremely small. The connections are then restored to their original condition. By alternately switching back and forth between the two conditions the residual error converges rapidly to zero. To assist in rapid slewing of the platform through 90 degrees upon each change of switching conditions, the voltage across a resistor 13 is impressed upon gyro 81 through capacitor 14, the time constant being small compared with the time intervals between change of switching conditions. The capacitor 14 blocks a steady flow of direct current so that the rapid slew circuit cannot affect the steady-state operation of gyro 81.

Title: An oil-water-gas separator with an impact deflector
Inventor: BROWN MICHAEL R
IPC: B01D17/00
Filed: 1996-10-04
Abstract: A momentum impact absorber, located in a vessel for separating an oil-water-gas mixture, comprises an inlet nozzle 16 and a dish-shaped deflector 20. A plurality of cylindrical posts 32 are arranged circumferentially around the nozzle axis defining a dispersion area. The mixture passes through the nozzle 16 and is deflected backwards in direction of arrows 52,54 to impinge against the vessel inner wall 12 and subsequently through the cylindrical posts 32 which create tortuous flow paths 34. The nozzle 16 is preferably surrounded by a cylindrical shroud 26. The cylindrical posts 32 are free of sharp edges to minimise shearing of oil droplets. The deflector 20 absorbs the high kinetic energy of the inlet fluid an thereby minimises droplet shearing and damage by "slugs" to the interior of the vessel.
